Abstract:
Object To isolate and identify the flavones from the flower of Paulownia tomentosa (Thunb.) Steud., which has been used as traditonal herb medicine in the treatment of some diseases. Methods The flavones were isolated by column chromatography and their structures were elucidated through spectroscopic analysis (NMR). Results Five flavones were isolated and identified as 5, 4′-dihydroxy-7, 3′-dimenthoxyflavanone (Ⅰ), 5-hydroxy-7, 3′, 4′-trimenthoxyflavanone (Ⅱ), diplacone (Ⅲ), mimulone (Ⅳ) and apigenin (Ⅴ). Conclusion All these compounds are obtained from the flower for the first time and the flavones should be as bioactive constituents.
